【Abstract】 The effects of oral Polyactin A have been studied in 38 patients with recurrent respiratory tract infections. All the patients examined had no T. B. infections prior to the administration of Polyactin A. A dose of 5mg/day was given to the patients with age below three and 10mg/day to the patients with age of three or above for three months. It was found that the total clinical effective rate was 94.7％: serum IgM level was increased after one month and still remained at a high level after three months. Ten of 17 patients with PHA negative turned postive and six of 8 patients with PHA postive had an increase in its positivity after the challenge with Polyactin A. There was no side-effect found in all the patients. This study suggested that an oral administration of polyactin A has the potentiation in immunity and is also good at the prevention and treatment of recurrent respiratory tract infections in children.更多还原
